iCHARLES F. WAR/RICK, OF` IVIORGANTOVN, WEST VIRGINIA, ASSIGNOR TO UNITED STATES WINDOW GLASS COMPANY, 0F MORGANTOWN, WEST VIRGINIA, A COR- :eoItA'I'IoN or wns'r VIRGINIA.

To all whom t may concern.'

Be it known that I, GHARLEs F. WARRICK, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of West Virginia, haveinvented a new and useful Cylinder-Splitting Apparatus, of which the following is a specification.

This invention is a device for splitting sections of window glass cylinders preparatory to the carrying on of the shawling, attening and annealing operations.

One of the objects of the invention is to provide a simple device capable of ac curately splitting a flatteninglength in mm1- mum time. A further object is to provide a device in which the splitting operation may be carried out mechanically and the functions of the apparatus automatically arrested when the proper cracking tension has been applied.

The invention will be hereinafter fully `set forth and particularly pointed out in l the claims.

"In the accompanying drawing?- Figure 1 is a perspectiveview illustrating an apparatus constructed in accordance with the invention. Fig. 2 is a side view thereof. Fig. 3 is an end view of the burner. `Fig. 4 is a longitudinal sectional view of the Fig. 5 is a perspective view illustrating a slight modification.

Referring to the drawings, 10 indicates the supporting legs of a frame provided with side bars 11 which support strips 12 having their inner edges 13`beveled. The support strips 12 may be of any suitable material, but is is preferred to construct them of- `wood `and to so space them that a flattening length C is supported between them and has its bearing uponthe beveled edges 13. n

. Extending longitudinally of the frame are guide rods or rails 14, which are passed through laterally disposed guide members 15, of a burner casing 16, provided with a plurality of burners 17. Each burner is l provided with nozzles for supplying both gas and air, the gas being supplied through a conduit 18 and the air through a conduit 19.

The burner casing 16 is reciprocated along the guides 15 in any suitable manner; .In the drawings, Fig. 1 the means for recip- Specication of Letters Patent.

`scratching the glass on said line. To ef-` fect this action a lever 28 is pivoted to the frame in a position to lie contiguous to the open end of the cylinder C, and pivoted to said lever is a scratching member 29, provided with a scratching point 30 of suitable material, a spring 31 being provided to hold thescratching point 30 in contact with the glass. The lever 28 is provided with an extension 32, carrying a switch member 33, coperating with contacts connected with the circuit wires 34 leading to the motor 25. The switch member is normally held in engagement with the contacts by means of an arm 35, pivoted at any suitable point, and provided with a protuberance, positioned to drop into a complemental recess in a disk 36, carried by a shaft 37, which is driven by a pinion 38, meshing with a gear 39 on the shaft 24.

In practice, when it is desired to start the apparatus, the operator grasps the handle of lever 28, and after first rocking scratching member 29 so that the abrasive point 30 will not touch the glass, he swings said lever 28 so as to move the switch member 33 into engagement with the contacts of the wires34, whereupon the motor 25 is energized, and the shafts 24 and 37 are operated. Rotation of the disk 36 elevates the arm 35 and holds the extension 32 in a positionto keep the circuit closed. As the cam 23 rotates the burner 16 is reciprocated longitudinally of the cylinder C, and the burners will direct very ne pointed flames against the said cylinder in a longitudinal line until a cracking tension is created. The gear 39 and pinion. 38 are so proportioned that by the time the cracking tension is applied the protuberance of arm 35 will drop intothe recess of disk 36, thereby perof the extension 32. This will permit the lever 28 to swing on its pivot and break the circuit to the motor 25, whereupon the parts will come to rest, and as said lever swings, the abrasive point 30 is dragged across the inside edge oi' the cylinder thereby starting a crack which splits the cylinder.

1n Fic'. 5 is illustrated a slight modification for manual operation. In this form, a rod A() is attached at one end to the burner casing 16 and provided at the other end with amhandle for convenient manipulation. The scratching of the cylinder is also carried out manually.

Having thus explained the nature oi. the invention, and described an operative manner oif constructing and using the same, al-

though without attempting to set forth alll of the iorms 1n which it may be made, or all ot' the `forms of its use, what is claimed is 1. A `cylinder splitting mechanism comprising a support having means for sustaining a glass cylinder, and means for applying heat to the under side oi said cylindery in a longitudinal line" to create a cracking tension along said line.

2. A cylinder splitting apparatus comprising a support having means for sustaining a glass cylinder, reciprocable means for applying heat to the under side of said cylinder, and means for guiding said heat applying means longitudinally o'l' the cylinder whereby a cracking tension is created.

3. A cylinder splitting apparatus comprising a support having means for sustaining a glass cylinder, a gas burner mounted below the plane ot the cylinder support, and means attached to said burner whereby it may be reciprocated longitudinally of the cylinder to apply a cracking tension.

et. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a guide positioned below the plane of the cylinder support, and a reciprooable burner engaging vsaid guide and positioned to apply a cracking tension in a line extending longitudinally of the cylinder.

5. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, means or applying heat to the under surface of said cylinder in a longitudinal line to create a cracking tension, and means for scratching the cylinder in register with said line.

6. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a gas burner, and means for reciprocating said burner longitudinally beneath the cylinder to apply a cracking tension to said cylinder.

7 A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a guide located in a plane below the cylinder support, a gas burner mounted on said guide, and means for reciprocating said burner along said guide.

8. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a guide located in a plane below the cylinder support, a gas burner, means Jor reciprocating said burner along said guide, and means tor scratching the cylinder in register with the line of reciprocation of the burner.

9. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a gas burner, means :tor reciprocating said burner longitudinally of the cylinder, and means for automatically arresting movement of said burner.

10. A cylinder splitting apparatus comprising a. support for sustaining a glass cylinder, a gas burner, a motor, means actuated by the motor for reciprocating said burner longitudinally of the cylinder, and means for automatically cutting o the power to said motor.

11. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a gas burner, a motor, a switch controlling tlie circuit to said motor, means actuated by the motor for reciprocating said burner longitudinally oi' the cylinder, and means governed by said reciprocating means for controlling said switch.

12. A cylinder splitting apparatus comprising a support for sustaining aglass cylinder, a gas burner, a motor, means actuated by the motor for reciprocating said burner longitudinally o'l' the cylinder, means for scratching the cylinder, and means for automatically cutting oil the power to the motor.

13. A cylinder splitting apparatus comprising a support for sustaining a glass cylinder, a gas burner, a motor, a pivoted arm controllng said motor, means actuated by the motor for reciprocating the burner longitudinally oi' the cylinder and means controlled by said reciprocating means for normally locking said pivoted arm against movement.
